I tried moving the Objective wheel, it works, caused program to stall though and I had to run Kill/Run to clear it. Tried changing the display gain from 2 (normal setting) to 16 and that improved it a little.

I'm not sure why the display looks so different, maybe it is related to having the Camera Controller off overnight on Thursday due to the powerline work by the contractors. DPMON COMMENT: Sat Mar 22 18:11:50 GMT 1997 The problem might be due to an oversize occulting disk, I will stop Patrol to experiment with other disks.

(even at a Display Gain of 16). The features on the disk and at the limb look normal though, it is just away from the limb that is different. Will leave it like that for now and see if things change in a few days.

Its as if the gain has decreased somehow.
